I'm not sure if this is intended or not, but I think there might be something weird. In the console page, when enabling an Integration (I tried authentications only so far), the page reloads. It gives a feel of an HTML <form> that does a POST because there was no event.preventDefault() called before the handler returned. I also used to get this when using React as my frontend, and I realized later that it was because I was only calling event.preventDefault() after my processing, and because it immediately reloads the page, I could not see that it was never called because there was something that caused exception in earlier calls, and the handler didn't return false nor prevented the default behavior, so the POST fired as expected, causing a page reload. Probably also because of buffered console, which caused delays before I could see anything on the dev console, I mean, it's not straightforward to debug.
